I found a very interesting add-on for Firefox called Furigana Injector. I'll paste some info taken from its website
Before installing Furigana Injector, you need to install XHTML Ruby Support
Quote:Furigana Injector is ...A feature I found specially interesting is:
the sum of these parts:
* GUI controls and help pages (javascript, image and html resources)
* Webpage-text parsing (javascript)
* Adjustable array of user's known kanji (javascript)
* Dictionary (C++)
* Webpage DOM manipulation to insert <RUBY> tags. (javascript)
Quote:* Adjustable array of user's known kanji (javascript)So you can show the readings for kanji you can't read yet, and hide the readings for the kanji you are supposed to know. I think that it is a very useful feature, and it may be even more useful if you are using Trinity.
